The xMnO(100-x)[2P(2)O(5). PbO] glasses were prepared with MnO concentratio
n being in the range of 0 less than or equal to x less than or equal to 50
mole fraction and were investigated by EPR spectroscopy and magnetic suscep
tibility measurements. Octahedral symmetric sites tetragonally distorted we
re detected for x less than or equal to 5 mole fraction MnO. Only Mn2+ ions
were identified in these glasses, involved in dipole-dipole interactions.
